SpaceX and European MNOs Joust Over OOBE Waiver

SpaceX and European mobile network operators are at odds over the out-of-band emissions waiver SpaceX is seeking for its supplemental coverage from space service (see 2408130008). In a letter to the FCC Space Bureau this week, Vodafone, Orange, Liberty Global, Telefonica, PPF, Telenor and United Group said they were "gravely concerned" about proposed lower safeguards protecting terrestrial MNOs from interference. They said the current aggregate out-of-band emission limit "represents the bare minimum level of protection that mobile network operators require from spurious emissions" in low- and mid-band spectrum. That current limit, they added, "should be regarded as a 'best case,'" as terrestrial MNOs could experience amplified interference when multiple competing direct-to-device satellite systems operate, or an individual D2D operator expands the number of satellites in orbit, prompting more coincident interference. In docket 23-135, SpaceX said the MNOs, all investors in rival D2D operator AST SpaceMobile, are on a "scorched-Earth campaign to hamstring" competition. They "provide zero technical support for their opposition" and don't address SpaceX and T-Mobile technical assessments showing adjacent-band terrestrial networks would be protected, SpaceX said. Nor do they provide any technical support for their "specious" best-case claims, it added. If the best-case claims are correct, SpaceX said, AST operations would cause far more interference to users than the protection level being demanded of SpaceX.
